In September 2003, Gary Meekin recognised that he could offer better quality, greater reliability and improved value for money within the manufacturing and recycling industry — and so General Maintenance & Diagnostics Ltd was born.
By the time the company was established, Gary had already spent over 20 years in the injection moulding industry. Initially, he began as a process technician, before later progressing to work as an engineer and technical support specialist at a local injection moulding and extrusion company. As a result, this hands-on industry experience laid the foundation for what has become a trusted Bolton engineering company, consistently serving businesses across the region.
GM Diagnostics supports clients as experienced Bolton engineers, proudly providing specialist diagnostics, repairs and maintenance solutions throughout the North West.
